Vertical AI video for Reels and TikTok
Choose the 9:16 format before the run and the clip is drawn for a phone screen from the start. Not every model handles vertical frames equally well, and the supported formats are listed on each model card. Check the format before you run, so the frame does not get cropped in editing.

Step by step
Choose the format
Set 9:16 in the clip settings. Do not make a 16:9 clip and crop it later, the composition suffers.
Keep the subject centered
In a vertical frame the main subject belongs in the middle third. Faces and the product should not drift to the edge.
Check on a phone
Watch the clip full screen on a phone. Small artifacts and captions show up there.

Frequently asked questions
What clip length works for Reels?
Short clips of five to fifteen seconds often work best in the feed. Each model page lists its supported range.
Can I turn a horizontal clip into a vertical one?
You can crop it, but part of the frame is lost. It is better to make it in 9:16 from the start.
Which models support 9:16?
The supported formats are on each model card. Open the model and check whether 9:16 is listed.
What background works for a vertical clip?
A simple background without small details. Small things get lost in a vertical frame, and the main subject must read at once.
Do vertical clips need captions?
Yes, many people watch without sound. Add large captions in editing, in the upper or middle part of the frame, so the platform interface does not cover them.
